Specification of Letters Patent. 1 Patented N 10, 1914.

Application filed m 1, 1914. Serial No. 848,436.

To all whom, it may concern:

Be it known that I, DALLAS L. IQEOK, a citizen of the United States,residing at Brookings, in the county of Brookings and State of SouthDakota, have invented certain new and useful Improvements inCultivators, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to certain improvements in cultivators, and theobject of the invention is to provide a novel and improved device ofthis general character wherein the requisite action upon the soilbetween the adjacent rows may be effected with convenience and facility.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improvedcultivator whereby certain important advantages are attained and thedevice is rendered simpler, less expensive and otherwise more convenientand advantageous for panying drawings, wherein- Figure 1 is a view intop plan of a cultivator constructed in accordance with an embodiment ofmy invention; Fig. .2 is a rear elevational view of the device asillustrated in Fig. 1; Fig. 3 is a side elevational view of the deviceas herein embodied; Fig. l is a detail sectional view, illustrating themeans herein employed for adjusting the cultivator blades or shovels;Fig. 5 is a longitudinal sectional view, showing in detail a mountingfor the shovels or blades; and Fig. 6 is a sectional view takensubstantially on the line 66 of Fig.

As disclosed in the accompanying drawings, 1 denotes an arch frameprovided at its lower extremities with the trunnions 2, on which thesupporting wheels 3 are adapted to bemounted, and operatively engagedwith such member 1 is the draft rigging 4: which may be of any ordinaryor preferred construction, herein disclosed as particularly adapted fora double team.

Rotatably supported by the frame 1 is the shaft 5 terminating at itsopposite ends in the cranks 6, to each of which is operatively comprisestwo sections capable of adjustment, as indicated at 14:, whereby thefree extremities of the member may be moved one relative to the other inorder to co1npcnsate for different widths of rows. I also find it ofadvantage to interpose between the crank ends 6 in the shaft 5 and theframe 9 a buffer 15, preferablya coil spring, surrounding the link 8whereby it will be seen that independent movement may be had by theauxiliary arch member 12 in such instances when an undue obstruction isencountered. The shaft 6 has coacting there with a conventional latchcontrolled lever 17 whereby sufficient rotation may be imparted totheshaft to raise or lower the auxiliary arch member 12 as thenecessities of practice may require.

Disposed transversely through each end of the auxiliary arch member 12is a tubular member 18, through which is disposed a shaft 19, on theopposed extremities of such shaft 19 are mounted the sleeves 20 to whichare suitably secured the shanks 21, the opposed faces of the sleeves 20and the tubular member 18 being of clutch formation so that the shanks21 may be adjusted on any desired inclination, such adjustment beingmaintained through the medium of the clamping nuts 22 suitably engagedwith the end portions of the shaft 19.

Operatively engaged with the lower or outer extremities of the shanks 21are the cultivator blades or shoes 23 which are also operativelyengaged, through the medium of the links 24, with the sleeve 25,slidably mounted upon a rod 26 projecting rearwardly from the lowerextremity of the auxiliary arch member 12 and operatively engaged withsuch sleeve 25 is a lever 27 whereby it will. be readily perceived thatthe blades or shovels 23 may be adjusted one relative to the other. i Ifind it of advantage to have the outer end of the rod 26 provided with aFrom the foregoing description, it is thought to be obvious that acultivator con structed 1n accordance with my invention 1s of anextremely simple and comparatively inexpensive nature and isparticularly Well adapted for use by reason of the convenience" andfacility with which it may be assembled, and it will also be obviousthat my invention is susceptible of some change and modification withoutmaterial departure from the principles and spirit thereof and for this:

between the sleeve and each of the implements, and means for impartinmovement to" the sleeve longitudinally of the rod.

2. A device of the character described comprising a supporting frame,anarch member adj ustably carried thereby, rods projecting from theextremities of the arch member, a sleeve slidable on each of the rods,an agricultural implement disposed on opposite sides of: the rod, a linkconnection between the sleeve and each. of the implements, means forimparting movement to the'sleeve longitudinally of the rod and anagricultural implement carried by the outer end of the rod.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
